Thanks everyone for your advice! We've decided on September 8-17th and will switch up our route a little by driving from S.F. to L.A. instead (spending the first 2 nights in S.F.) and making Yosemite our first overnight stop along the way. Our other O/N stops will be in Santa Cruz and Santa Barbara and we'll finish off the vacation with 3 days in L.A. I've been to all of the places where we are staying overnight but we are looking forward to making lots of stops in between. Are there any particular landmarks/places we should make time to stop and enjoy en route? Thanks again!
